Remove chart version from deployments and services selectors (#1562)

Label selectors are immutable; having the chart version part
of the label selectors means that upgrades require a full
recreation of the deployments and services instead of a simple
update.
This branch removes the chart version from the selectors
to allow smooth upgrades.
